need help making a call

When I'm outside it's hard enough to dial and see a number let alone having to do it twice on this phone.Is there a way I can only have to tap my phone once to make a call.Even in favorites it's the same.
Sometime it take's up to four taps just to make a call.
Phone,contacts,pick the contact,then hit the little green icon.
So is there a way or program I can use.
THANK'S
